There are manual oil extractors about the size of a grease gun that you can pull on a plunger to extract oil but would require several uses to extract any large quantity of oil. They are used primarily to lower the level of an overfilled crankcase. Not sure what equipment you are working on but bear in mind that some gear boxes or transmissions have internal filters and magnets that require cleaning or replacing as well as internal adjustments when the pan is off. Some small equipment manuals show where you can drill and tap holes for more convenient draining. The oil extractors that I have used have left me less than satisfied with the results since they never seem to do a complete job of extraction and the oil looks dirty soon after. If there is an oil cooler then the outlet line can be removed and placed in a bucket to drain while you add oil in the fill cap while the unit is running. You can monitor the outlet oil until it looks clean but this usually requires more oil than a normal oil change.
Instead of a plastic bucket, get a 1qt to 1 gal glass jar (mason/bell canning jar or bulk pickle/relish jar). I don't think a vacuum cleaner can pull enough vacuum to cause the jar to implode.
I turned my oiless air compressor into evacuator by putting a hose from the intake on the pump to the tank. With a ball valve and a vacuum guage between the intake and tank . Drilled a hole on top of the tank put a brass fitting with hose that will be used to evacuate fluids. And a clamp to close off that end when pulling vacuum. The proceedure . Open ball valve clamp other end so it s airtight. Turn on compressor. When it get to 20 psi close ball valve .with the other end in the fluid release clamp. Works great. Lol if you have a spare compressor
Your pipe size need to be between 6mm to 4mm to reach nook and cranny. It also needs to be longer on 71cm or more. I am saying this because you have to this on dipstick mostly. So it can suck everything 100%. And you must warm up the engine oil. So oil can flow faster. Plus replace plastic bucket to metal/glass jars to avoid shrinkage.
Use a more rigid HDPE type hose instead of the squishy poly hose. Refrigerator ice maker hose is easy to find. You can straighten the curly HDPE hose with boiling water (1 minute) and then straighten it out to cool.
Fit a Clunk on the see through pvc pipe end. Drop in old container. Old container higher ground. Start Syphon the old oil and leave it on its own till finished syphoning. Meanwhile you can go on making something new. Still a good clean show you put on. Thanks.
Great concept and build. Like you said it will work if you have a steel bucket. What if there was air pressure pushing/blowing on the oil while the vac is sucking?
Check out the pneumatic brake bleeders and maybe you will come up with idea from the concept it allows ait to pass through so vacuum doesn't implode bottle
Take the orange bucket cut 4 inches off the top and 2 inches off the bottom the slide the middle into the white pail tap down until tight . Seal up best you can try again .
I had same problem and it was SOLVED ! I put the receiving container inside the shop vac rather . Only had to use 1 hose . I found this by experimenting and watching Chris Notap on TH-cam. No need and expense to build a meta tank. Here is the Video link. th-cam.com/video/Uk46vCOGTFI/w-d-xo.html. I also enjoy your knot tying videos....great job.
Add an adjustable pressure relief valve to the bucket lid; set the relief pressure to just before the bucket begins to collapse upon itself.

Put a valve on the vacuum side so you can add and hold vacuum.

That’s a good idea, strengthen the center.
@@txtoolcrib maybe . Only one wat to find out ! Lol . Keep us informed 👍
We use 55 gallon vacuum drums very similar to this for sucking machine sumps. Maybe a pneumatic approach if you have air in your shop
I was actually thinking that very same thing, with a 30 gallon drum.

Nice
It sucks. But then again, it's supposed to. 😉😁
Lol.
metal drum
Look at some professional ones to get more ideas for improvements.
